Bug reference:      5629

PostgreSQL version: 8.3.11
Operating system:   Linux
Description:        ALTER SEQUENCE foo START execute a RESTART
Details:

Steps to reproduce:

CREATE SEQUENCE foo;
SELECT setval('foo',12345);
ALTER SEQUENCE foo START WITH 10; -- can't change value
SELECT nextval('foo'); -- it's 10 instead of 12346

Apparently START is executing a RESTART.
